Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Toxic effects of substances chiefly nonmedicinal as to source
      (T51-T65)
      • Toxic effect of other gases, fumes and vapors
        (T59)

T59.0X3D is a billable diagnosis code used to specify a medical diagnosis of toxic effect of nitrogen oxides, assault, subsequent encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

T59.0X3D is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like toxic effect of nitrogen oxides assault. According to ICD-10-CM Guidelines a "subsequent encounter" occurs when the patient is receiving routine care for the condition during the healing or recovery phase of treatment. Subsequent diagnosis codes are appropriate during the recovery phase, no matter how many times the patient has seen the provider for this condition. If the provider needs to adjust the patient's care plan due to a setback or other complication, the encounter becomes active again.

Clinical Classification

Clinical Information

  • Blood Urea Nitrogen

    the urea concentration of the blood stated in terms of nitrogen content. serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes. (from saunders dictionary & encyclopedia of laboratory medicine and technology, 1984)
  • Dissolved Organic Matter

    a heterogeneous class of water-soluble compounds containing covalently bound carbon that are derived from a variety of biological and geological sources during the biogeochemical cycling of carbon (carbon cycle).
  • Inert Gas Narcosis

    progressive mental disturbances and unconsciousness due to breathing mixtures of oxygen and inert gases (argon, helium, xenon, krypton, and atmospheric nitrogen) at high pressure.
  • Lasers, Gas

    lasers in which a gas lasing medium is stimulated to emit light by an electric current or high-frequency oscillator.
  • Mannomustine

    nitrogen mustard derivative alkylating agent used as antineoplastic. it causes severe bone marrow depression and is a powerful vesicant.
  • Mechlorethamine

    a biologic alkylating agent that exerts its cytotoxic effects by forming dna adducts and dna interstrand crosslinks, thereby inhibiting rapidly proliferating cells. the hydrochloride is an antineoplastic agent used to treat hodgkin disease and lymphoma.
  • N-Glycosyl Hydrolases

    a class of enzymes involved in the hydrolysis of the n-glycosidic bond of nitrogen-linked sugars.
  • Nitric Oxide

    a free radical gas produced endogenously by a variety of mammalian cells, synthesized from arginine by nitric oxide synthase. nitric oxide is one of the endothelium-dependent relaxing factors released by the vascular endothelium and mediates vasodilation. it also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. nitric oxide activates cytosolic guanylate cyclase and thus elevates intracellular levels of cyclic gmp.
  • Nitrogen

    an element with the atomic symbol n, atomic number 7, and atomic weight [14.00643; 14.00728]. nitrogen exists as a diatomic gas and makes up about 78% of the earth's atmosphere by volume. it is a constituent of proteins and nucleic acids and found in all living cells.
  • Nitrogen Compounds

    inorganic compounds that contain nitrogen as an integral part of the molecule.
  • Nitrogen Cycle

    the circulation of nitrogen in nature, consisting of a cycle of biochemical reactions in which atmospheric nitrogen is compounded, dissolved in rain, and deposited in the soil, where it is assimilated and metabolized by animals, plants, bacteria, and fungi, eventually returning to the atmosphere by bacterial decomposition of organic matter.
  • Nitrogen Dioxide

    nitrogen oxide (no2). a highly poisonous gas. exposure produces inflammation of lungs that may only cause slight pain or pass unnoticed, but resulting edema several days later may cause death. (from merck, 11th ed) it is a major atmospheric pollutant that is able to absorb uv light that does not reach the earth's surface.
  • Nitrogen Fixation

    the process in certain bacteria; fungi; and cyanobacteria converting free atmospheric nitrogen to biologically usable forms of nitrogen, such as ammonia; nitrates; and amino compounds.
  • Nitrogen Isotopes

    stable nitrogen atoms that have the same atomic number as the element nitrogen but differ in atomic weight. n-15 is a stable nitrogen isotope.
  • Nitrogen Mustard Compounds

    a group of alkylating agents derived from mustard gas, with the sulfur replaced by nitrogen. they were formerly used as toxicants and vesicants, but now function as antineoplastic agents. these compounds are also powerful mutagens, teratogens, immunosuppressants, and carcinogens.
  • Nitrogen Oxides

    inorganic oxides that contain nitrogen.
  • Nitrogen Radioisotopes

    unstable isotopes of nitrogen that decay or disintegrate emitting radiation. n atoms with atomic weights 12, 13, 16, 17, and 18 are radioactive nitrogen isotopes.
  • Nitrogenase

    an enzyme system that catalyzes the fixing of nitrogen in soil bacteria and blue-green algae (cyanobacteria). ec 1.18.6.1.
  • Nitrogen-Fixing Bacteria

    bacteria that are capable of nitrogen fixation.
  • Nitrogenous Group Transferases

    enzymes that catalyze the transfer of nitrogenous groups, primarily amino groups, from a donor, generally an amino acid, to an acceptor, usually a 2-oxoacid. ec 2.6.
  • Nitrous Oxide

    nitrogen oxide (n2o). a colorless, odorless gas that is used as an anesthetic and analgesic. high concentrations cause a narcotic effect and may replace oxygen, causing death by asphyxia. it is also used as a food aerosol in the preparation of whipping cream.
  • PII Nitrogen Regulatory Proteins

    a family of signal transducing adaptor proteins that control the metabolism of nitrogen. they are primarily found in prokaryotes.
  • Reactive Nitrogen Species

    nitrogenous products of nitric oxide synthases, ranging from nitric oxide to nitrates. these reactive nitrogen intermediates also include the inorganic peroxynitrous acid and the organic s-nitrosothiols.

Coding Guidelines

The appropriate 7th character is to be added to each code from block Toxic effect of other gases, fumes and vapors (T59). Use the following options for the aplicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Present on Admission (POA)

T59.0X3D is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

Convert T59.0X3D to ICD-9-CM

  • ICD-9-CM Code: V58.89 - Other specfied aftercare
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Table of Drugs and Chemicals

The parent code T59.0X3 of the current diagnosis code is referenced in the Table of Drugs and Chemicals, this table contains a classification of drugs, industrial solvents, corrosive gases, noxious plants, pesticides, and other toxic agents.

According to ICD-10-CM coding guidelines it is advised to do not code directly from the Table of Drugs and Chemicals, instead always refer back to the Tabular List when doing the initial coding. Each substance in the table is assigned a code according to the poisoning classification and external causes of adverse effects. It is important to use as many codes as necessary to specify all reported drugs, medicinal or chemical substances. If the same diagnosis code describes the causative agent for more than one adverse reaction, poisoning, toxic effect or underdosing, utilize the code only once.

Patient Education


Poisoning

A poison is any substance that is harmful to your body. You might swallow it, inhale it, inject it, or absorb it through your skin. Any substance can be poisonous if too much is taken. Poisons can include:

  • Prescription or over-the-counter medicines taken in doses that are too high
  • Overdoses of illegal drugs
  • Carbon monoxide from gas appliances
  • Household products, such as laundry powder or furniture polish
  • Pesticides
  • Indoor or outdoor plants
  • Metals such as lead and mercury

The effects of poisoning range from short-term illness to brain damage, coma, and death. To prevent poisoning it is important to use and store products exactly as their labels say. Keep dangerous products where children can't get to them. Treatment for poisoning depends on the type of poison. If you suspect someone has been poisoned, call your local poison control center at 1-800-222-1222 right away.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
